Х Blind spots (dark green area) 2.

The radar sensors monitor the lanes immediately to the left and right of your
vehicle. Other lanes are not covered by the sensors.

Note

The side assist system is programmed for lanes of a fixed width, and is not
able to measure differing lane widths. It monitors a zone equivalent to one normal
lane width on either side. If the lanes are narrower than this, or if vehicles are
not travelling in the centre of the lanes, the system may register vehicles that
are not in fact travelling in an adjacent lane.
